Sorry for delay. I don't know why but I totally missed these posts and I thought this challenge was not attractive.
Illuna, Apex of Compleation/
pernicious It is very flavorfully depicting Phyrexian invasion.
It allows you to mutate only once for each creature in most cases.
It is less exciting than mutate but also less problematic on playability and is polished up in total balance.
Ashling the Flamespark/
vizionarius At first, I couldn't get how it works. As now I got it, I feel it is indeed impressive.
Wizards says that MoM will change the Multiverse forever.
And the Mending, the last time it had been changed, was the reason why we can summon PW.
So I am forecasting that something that changes both MtG's mechanic and flavor will come other than battle.
The ability is enough attractive probably for many people.
One thing that bothers me is that it uses two types of counter both are counterable thing.
It might have more playability if it uses only loyalty counters and has "gets +1/+1 for each loyhalty counters on it".
Schemer of Millenia/
Idea It almost assures the win if it could survive a turn after you hard cast it.
It has no immunity against removal spells so I guess the most players who tried to use this card as a finisher would finally exchange it with another one.
But anyway it has an strong attraction which would make many players want to use it in aspects of both ability and flavor.
And there's no doubt about that it is very strong once it survives a turn so it is possibly a good finisher for some decks.
Winner
Winner is
vizionarius .
Once I hesitated to give Ashling the win because the mechanic seemed to be limited for rare or mythic and not suitable for the feature of a set.
But if the ability appears in uncommon like WotS, it can be said the feature of a set.
The zero initial loyalty and weakness of being both a creature and a planeswaler seems to be easier to balance it for R&D.
The deciding factor is that it finely work with proliferate.
the runner up is pernicious. The compleat is flavorful and can be used for common cards and perfectly matches with Phyrexia.
I like Idea's one as the card itself for I am a Bolas fan, but I doubt infect will be beck at now we have toxic, which is a tuned infect.
Thank you for your participation.
